Housing and Power Supply

Connection to an electrical power outlet restricts the portability ofthe electronic device 100. A battery can provide the power needed by theelectronic device 100 while permitting portability.

Embedded batteries for electronic devices adopt a high-cost flexibleprinted circuit board (FPCB) and suffer from an insufficient mountingspace for a coupler to connect the FPCB to the board of the portableterminal. To connect the board of the electronic device with theembedded battery, a connector is placed on the FPCB. Installing theconnector results in a waste of space and time. Producing a battery packfor electronic devices requires manual work to wrap an insulating filmaround a battery and seat the battery pack in the space, increasingassembly costs.
